CALVIN B. SIBERT, OF GORDONSVILLE, VIRGINIA.

HORSE-DETACHER.

SPECIFICATION formingpart of Letters Patent No. 226,560, dated April 13,1880.

Application filed November 29, i879.

To all whom it may concern:

Be it known that I, CALVIN B. SIEERT, of Gordonsville, in the county ofOrange and State of Virginia, have invented certain new and usefulImprovements in Devices for Detaching Horses from Vehicles, of which thefollowing is a specification.

This invention relates to that class of devices employed to detachunmanageable horses from vehicles; and the object of the invention is tosimplify the construction of such devices and render them more effectivein operation than heretofore.

The invention consists, essentially, in the combination, with theordinary single tree, splinter-bar, and a detachable bolt, whichconmeets the two together, of a semi-elliptical or how spring arrangedlongitudinally between the single-tree and splinter-bar in such mannerthat when the lower end of the bolt is released the reaction orresiliency of the spring will throw the single-tree upward anddisconnect the pin or bolt from the splinter bar, thereby freeing thehorse from the vehicle. The end of the bolt which projects below thesplinter-bar is locked by one end of a pivoted lever, the other end ofwhich is connected to a cord extending to the vehicle, and by pullingsuch cord the lower end of the bolt will be released, permitting thespring-plate to come into action.

In the accompanying drawings, Figure 1 represents a perspective view ofa portion of the shafts of a vehicle embodying my invention; Fig. 2, alongitudinal section of the splinterbar and actuating-spring, with thesingle-tree partly in section; Fig. 3, a plan view of a carriage-polewith my invention applied thereto.

Referring to the drawings, the letter A indicates the shafts of avehicle, B the splinterbar, and O the single-tree, all of which are ofthe ordinary construction. The pin or' bolt D, which connects the single-tree to the splinter-bar, is also of the usual construction, but atits lower end is provided with a transverse aperture, (0, into whichsets one end, I), of a lever, E, which is arranged along the under sideof the splinter-bar, and is pivoted thereto at 0, and one end, d, of thesaid lever is connected with a cord, 0, which extends to the vehicle inreach of the occupant, the object of which is to readily release thelower end of the pin or bolt D by drawing on the cord, for a purpose tobe hereinafter explained.

The upper side of the splinter-bar is provided with a metallic plate, F,having near each end a vertical projection, f and between thesingle-tree and splinter bar is longitudinally arranged asemi-elliptical or bow-shaped spring, Gr, having at each end anelongated slot, g, which set over the projections f on the face-plate Fand retain and guide the ends of said spring in proper position. The pinor bolt D passes through a central openingin the single-tree,semi-elliptical spring, and splinter-bar, and the single-tree is forceddown to compress the spring, after which the hooked end b of the pivotedlever E is caused to engage the aperture c in the pin, therebymaintaining the spring in its compressed condition. Thus, should theanimal become unmanageable, by drawing the cord e to release the leverfrom engagement with the pin or bolt, the reaction or resiliency of thesemi-elliptical spring will act to suddenly throw the single-treeupward, which carries with it the connecting pin or bolt and disconnectsthe same from the splinter-bar, thereby freeing or detaching the animalfrom the vehicle.

In order to relieve the connecting bolt or pin D from lateral pressureor strain in drawin g the vehicle, which would be liable to affect theperfect action of the spring, I provide theholdback on the shafts whichis open at its a dinary double-tree takes the place of the splinter-barof the shafts, as shown in Fig. 3.

Heretofore devices for detaching horses have been constructed in whichare employed a bolt for detachably connecting the single-tree to thesplinter-bar. said bolt being attached at its lower end to a lever, bywhich it can be rotated to bring the rectangular upper end intocoincidence with a rectangular opening in the sin gletree, a cylinderoperated by a coiled spring being forced into another cylinder when thesingle-tree is placed on the splinter-bar, and which coiled spring isintended to throw the single-tree off the connecting-bolt whenever therectangular head of the latter is brought into coincidence with thecorrespondinglyshaped opening in the single-tree. Such construction ofdevices is open to several objections, the most serious of which resultsfrom the fact that it is difficult to revolve the connect-ing-bolt soaccurately as to bring its rectangular head in coincidence with thecorrespondin g opening in the single-tree, and unless the parts areaccurately adjusted the coiled spring cannot perform its function. Thisobjection is obviated by my invention.

Having fully described my invention, what I claim is- 1. The combinationwith the single-tree, and a pin or bolt connecting the same to thesplinter-bar or double-tree, and means for looking and unlocking the pinor bolt, of a semielliptical or how spring arranged longitudinallybeneath the single-tree, substantially as CALVIN B. SIBERT.
